7 benefits of collagen supplementation

What are the benefits of collagen supplementation?

Collagen is an extremely versatile protein that plays a fundamental role in many aspects of human health. It influences the condition of the skin, improving its firmness, elasticity and strength, so that the skin remains smooth and tight even in later life, and it strengthens the structure of the hair and nails, preventing breakage and splitting. In addition, collagen is essential for the proper functioning of joints, improving their flexibility and facilitating smooth movement, and is therefore an effective support for athletes, physically active people and those dealing with injuries. It is also worth noting the beneficial effects of collagen on the digestive and circulatory systems. It supports metabolic processes and the maintenance of adequate blood pressure, contributing to better circulation and the proper functioning of the cardiovascular system.

Maintaining optimal levels of collagen in the body benefits every aspect of our body. It provides effective support for the joints, skin, hair, nails, bones, muscles, digestive system and also the immune system. Therefore, in order to enjoy the comprehensive effects of collagen on the body’s health and wellness, it is advisable to ensure adequate supplementation.

1. collagen for joints

Collagen makes up around 60% of the dry weight of articular cartilage, which is essential for efficient daily movement[1]. Its adequate levels in the body translate into freedom of movement and physical activity, while its lack, to emerging joint problems and comfortable movement.

How does collagen help your joints?

• Participates in the production of joint fluid and the maintenance of its normal viscosity
• Rebuilds cartilage tissue, improving its synthesis, preventing degradation and promoting hydration and flexibility
• Improves joint flexibility, ensuring free joint movement
• Prevents degradation of joint cartilage, ensuring its resilience and flexibility thanks to the collagen fibre networks formed
• Supports the regeneration process of joints after injury, rebuilding bones and muscles

Many people start to lose their collagen reserves as early as 25 years of age, which can result in visible deficits in the condition of the joints. Athletes and physically active people, especially those involved in extreme sports, are most at risk of problems with their proper functioning. A 24-week study showed that collagen hydrolysate supplementation helps to reduce joint pain in athletes[2]. This is a particular group of people who should consider collagen supplementation for joints.

2. collagen for hair

Collagen is an indispensable element in hair care, positively influencing its appearance, condition and health. Regular supplementation brings visible results, making hair stronger, shinier and less susceptible to damage, translating into attractive appearance and health.

How does collagen take care of the condition and appearance of hair?

• Works with keratin – supports the production of keratin, which is the foundation of the hair structure. As a result, adequate levels of collagen contribute to increased hair strength, preventing damage.
• Stimulates hair growth – collagen improves blood circulation in the scalp and strengthens hair follicles, promoting better access to nutrients needed for hair growth.
• Delays the greying process – thanks to its ability to combat oxidative stress, collagen can prevent or slow down hair colour changes and the ageing process.
• Moisturises and rebuilds – collagen helps to maintain adequate moisture in the hair, promoting elasticity and resilience. Moisturised hair is more resistant to damage and external environmental factors.
• Strengthens their condition – as one of the main building blocks of the hair structure, collagen strengthens its strength and resistance to damage, preventing breakage, splitting and hair loss.

All of the above properties make collagen supplementation for hair an invaluable support for both its appearance and health.

3. collagen for the skin

Collagen plays an extremely important role in maintaining the health and appearance of skin, especially facial skin. It is the main component of the dermis, responsible for as much as 80% of its dry weight. In addition to its basic structural functions, collagen’s role on the skin includes influencing its elasticity, hydration and regeneration.

How does collagen help the condition of the skin?

• Increases skin elasticity and firmness
• Improves skin hydration through amino acids such as glycine, lysine and proline
• Regenerates the skin through its ability to accelerate the cell renewal process
• Reduces the appearance of wrinkles and fine lines
• Supports the skin’s protective barrier against harmful external factors such as UV radiation, environmental pollutants and toxins

Collagen for wrinkles

The face is particularly prone to the formation of wrinkles, as these muscles are constantly relaxed and tightened during daily facial gestures. Collagen supplementation has a number of benefits for the skin, including reducing the appearance of wrinkles, improving firmness, smoothing texture and brightening the skin.

In one study conducted in 2023, oral collagen supplementation was proven to be an effective support against skin ageing. It was shown to have a specific effect on increasing hydration and elasticity and reducing skin wrinkles[3]. The use of collagen on wrinkles can help to reduce their appearance and delay their formation.

Collagen for scars after surgery

Collagen plays an important role in the scar healing process by influencing the structure and elasticity of the skin. Its supplementation can help to strengthen the dermis layer and increase its thickness, promoting better stretching of scars and reducing their visibility[4].

However, it should be noted that there is an important difference between collagen used as a dietary supplement and that used in cosmetics. Collagen that is delivered in the form of dietary supplements has the ability to penetrate into the deeper layers of the skin, affecting its structure from within. Collagen applied directly to the skin through cosmetics does not have this effect.

Collagen for stretch marks

Collagen plays an important role in the prevention and treatment of stretch marks by providing the skin with the elasticity and resilience needed to minimise the effects of stretching. In order to maintain a healthy skin structure and reduce the appearance of stretch marks, it is important to supply the body with an adequate amount of it.

It is worth knowing that the use of cosmetics with collagen, such as creams or lotions, as opposed to internal supplementation, may not produce satisfactory results. The reason for this is that the collagen molecules are too large to penetrate the outer layer of the skin. As a result, the effect of collagen cosmetics is usually superficial and short-lived. If you want a visible and long-term effect of collagen on stretch marks, instead of creams with collagen in them, reach for dietary supplements.

Collagen for cellulite

Collagen supplementation helps to increase skin firmness, improve hydration and increase skin density. As a result, it has a smoothing effect on the surface of the skin, reducing the appearance of lumps and dimples characteristic of cellulite.

The beneficial effects of collagen on cellulite are proven by a 2015 study published in the Journal of Medicinal Food. It looked at the effects of bioactive collagen peptides on moderate cellulite of 105 normal-weight and overweight women aged between 24 and 50 years. The women received 2.5 g of collagen daily for six months. The result was a significant improvement in the appearance of cellulite, as well as an increase in collagen integrity. This effect was particularly pronounced among normal-weight women[5].

Collagen for acne

Collagen is not a treatment for acne, but it does provide support for skin struggling with the problem. As with scarring, acne leads to a break in the skin, the healing process of which can be accelerated by collagen, helping to reduce acne.

A particularly important feature of collagen in the context of acne prevention is that it helps to maintain proper skin hydration. Dry skin can promote excess sebum production, which in turn increases the risk of acne. Additionally, by stimulating skin cell renewal, collagen can be helpful in reducing scars and discolouration left behind by acne.

4. collagen for nails

Collagen plays an important role in maintaining healthy nails, providing a strong structure and effectively counteracting brittleness and damage. In addition, collagen contributes to maintaining the uniform colour of the nail plate and a smooth, glossy surface. According to scientific studies, collagen supplementation can reduce nail brittleness by up to 42%.

A 2017 study found that at least four weeks of collagen supplementation reduces nail brittleness by up to 42%, while promoting nail growth by up to 12%. Additionally, up to 64% of study participants saw an overall clinical improvement in brittle nails within just 4 weeks of starting supplementation[6]. If you are struggling with problematic nails prone to frequent breakage and damage, nail collagen supplementation may prove to be an effective step in taking care of their strong structure and attractive appearance.

5. collagen for bones

Collagen plays an important role in bone structure, forming a dense network of fibres on which calcium, phosphorus and magnesium, among others, are deposited. In this way, it increases the hardness and strength of the bones. Insufficient levels of collagen lead to weakened bone tissue and an increased risk of fractures.

How does collagen help the bones?

• Strengthens their structure and density
• Reduces bone deterioration
• Influences their resistance to damage

6. collagen for the gut

Collagen manifests numerous benefits for gastrointestinal health, such as strengthening the intestinal membrane and reducing inflammation. Collagen acts as a natural antioxidant, helping to neutralise free radicals that can damage intestinal cells, leading to a variety of health problems.

The beneficial effects of collagen on gut health are being proven by an increasing number of scientific studies. One of these is a 2022 experiment conducted on mice. In it, collagen supplementation was shown to contribute to a reduction in pro-inflammatory gut bacteria[7]. Another study from the same year was conducted on women with gastrointestinal disorders. Taking about 20 g of collagen per day was proven to reduce bloating and relieve digestive symptoms. These effects were observed after six weeks of supplementation[8].

7. collagen for muscles

The use of collagen in combination with strength training contributes to increased muscle mass, strength and fat reduction. Researchers suggest that collagen’s beneficial effects on muscle are due to its ability to stimulate the production of proteins responsible for building and growing muscle tissue.

The beneficial effects of collagen on muscle mass are proven by research. In 2015, an experiment was conducted involving participants who supplemented with collagen for 12 weeks while also doing regular strength training. The study showed a more pronounced increase in muscle mass and strength, as well as more effective fat loss, compared to a control group that took a placebo[9].

In addition: Collagen for immunity

Collagen contributes to the body’s resistance to infection and supports its ability to fight pathogenic agents. It has a defensive effect, protecting the body from the effects of microorganisms and toxins, and supports the tissue regeneration process, promoting the restoration of damaged structures and the body’s overall immune capacity.

What are the properties of collagen?

Collagen is an extremely important dietary ingredient, supporting the health and fitness of the body on many levels. Among the most important properties of collagen are:

• Water-binding capacity – contributes to maintaining the skin’s hydration level. This keeps the skin hydrated, smooth and radiant, and helps nails and hair resist breakage and splitting.
• Maintaining skin integrity – prevents sagging and drooping of the skin, helping to maintain a youthful appearance and delay the ageing process.
• Regeneration – supports the repair and regeneration processes of joint and bone tissues, helping to rebuild damaged structures and accelerating the healing of wounds and scars.
• Antioxidant properties – thanks to bioactive peptides that help fight the harmful effects of oxygen in the body, collagen can help the body fight diseases such as cancer and atherosclerosis.
• Antimicrobial properties – fish collagen has peptides that fight bacteria that can cause a variety of infections in the body, such as skin infections and tooth decay.

What are the uses of collagen?

Collagen is used as an ingredient in skin care, skin, hair and nail strengthening cosmetics, in dietary supplements as their base or supplement, and in medicine, where it is used in implants, dressings and other medical devices.

• Collagen in cosmetics: the application of collagen to the surface of the skin helps to increase hydration and improve elasticity. For this reason, it is a common ingredient in face creams and body lotions. Collagen is also commonly used in hair care cosmetics, with the aim of strengthening hair structure and preventing breakage and excessive hair loss. Its addition can be found in the formulation of cosmetics for dry, damaged and excessively falling hair.
• Collagen in supplements: collagen in the form of dietary supplements is a simple and effective support for a variety of functions in the body. Collagen supplementation supports the condition of the skin, joints, hair, nails and supports the integrity of the gut and digestive system. Collagen preparations are available in a variety of forms, such as collagen for drinking, powder, jelly or tablets.
• Collagen in medicine: collagen also has applications in medicine, where it is used in the manufacture of implants, dressings and other products used during or after surgical procedures. Its ability to accelerate the skin’s healing process makes it an ingredient often used in medical products designed to aid the regeneration of skin tissue.
